Secondary analyses of a trial with back pain patients comparing a psychosocial intervention to usual primary care showed that profiles of patients responding favorably to treatment differed between intervention groups even though the effects measured at group level showed no difference at all [ 50].
Responsiveness, the degree of progression of radiological joint damage above the measurement error, is best determined by the smallest detectable change (SDC = ±1.96 × SDΔ (change scores between raters)/(√k × √2), where 'k' represents the number of readings or raters used for the actual analyses of a trial.
